should i get a 125 2 stroke or a 250 four stroke. i know the 4 stroke is better but is more expensive. also requires more maintence. which one sould i get?  

the 4 stroke doesnt require more maintenance. you do the valves once a year and a top end once every year and a half. the 250f is way better for resale value also. i would get the yz250f or crf250r.  

It all depends on what you wan't the bike for!  

i wouldnt recomend a 125 because i dont like the power at all. the minimum cc in 2 stroke i would go with is the ktm 144.  

ya bro don't get a 125 2-stroke......i have one...you end up running it to hard...trying to wrench out every little bit of power the bike has..........and end up doing this
 

melted the piston!!!!
 

all work done by yours truly woodsrideradam
 

isnt it expensive to replace the valves and top end evry year though?
